The TS118 integrated circuit device combines a 350V
normally closed (1-Form-B) relay with an optocoupler
in a single package. The relay uses optically coupled
MOSFET technology to provide 3750V
rms of input to
output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
The TS118 enables telecom circuit designers to
combine two discrete functions in a single component
that uses less space than traditional discrete
component solutions.
